COMBUSTON-ENGNE GOVERNGR.

Application filed Sept-einher 21, mile.

To all whom it may concern:

Be it known that I, EMIL Klier, a citizen of the Republic lofSwitzerland, resident of Winterthur, Canton of Zurich, Switzerland, haveinvented the following-described lmprovementsv in Combustion-EngineGovernors. ,i

The invention consists in the combination of parts and mode of operationand adjustment of centrifugal governors intended for thecontrol of thefuel supply, or other speed controlling organ, of internal combustionengines, more especially combustion enlgines used for propellingvehicles through electric-generator-motor transmission.

It is desirable to operate combustion engines at more than one normal speed, retaining governor control of the engine speed at all speeds. Forinstance, in the vehicle having electric transmission, it is oftendesirable to run the engine at a fixed higher speed during thepropulsion of the vehicle and at a fixed lower speed when thewheeldriving electric motors are at rest, and in both cases it isdesirable that the governor shall exert the same character ot' controlupon the engine, that is to say, shall respond equally to equalfluctuations. My invention'provides simpleand effective means for thepurpose, and which are particularlyv adapted to accommodate orcompensate the different conditions of vibrations and motions of thevehicle when the latter is in motion and at rest.

In the drawing forming part hereof, Figure l is a central longitudinalsection of a' governor, with parts 'in elevation, including the governorlever of the engine. the engine itself being omitted as unnecessary toan 5ufi'lerstanding of the invention; Fig. 2.

shows sectional details of the control rod in two positions, as laterdescribed; Fig. 3 is a perspective view of the governor; and Fig.

The governor lever 1 may be assumed to "be organized with the engineproper, not Ishown, in any suitable way, for instance, so as to controlthe suction valve of the fuel pump of Diesel type engines, or any otherSpecipetion of Letters Eatent.

the speed at which the engine runs. The

Ahollow spindle 2 may be assumed to be geared to theengine crank-shaftso as to be rotated thereby. T his governor spindle carries fast upon ita spider bracket 3, on which are pivoted two pairs of oppositely-ball-levers. These are marked 4 and 4, respectively, and each leverof' each pair is abell-cranlr lever with its longer arm normallyupstanding and carrying the y-ball, and its shorter arm proi'ectedradially toward the axis of the spindle. The fulcro.. of' the severallevers. marked 5, are indicated as equipped with ball bearings, of'conventional type, and the ends of the several short arms are providedwith hall-bearing rollers, marked 6 and 6a, respectively. These rollersare adapted to thrust upwardly upon the bottom side of a spring-loadedthrust collar 7, which forms the lower part or end of a dash potcylinder 8, which latter is fitted to slide on the `governor spindle 2,and is intended to be filled with oil or other mobile medium. rThedash-pot piston 9 is fixed to the spindle so that movement of' thecollar'i and cylinder 8 in eitlierdirection on the spindle is retardedor damped by thc resistance opposed to the passage of the liquid throughor past the piston. Above the range of motion of the dash-pot cylinder,the spindle Z also carries. screwed thereon. an abutment 10 for thegovernor spring 1l, the other end of which abuts against the collar 7,opposing upward movemerit of the latter, as produced by tlieflyballlevers, and tending to hold them upright.

sulting from its engagement by the fly-ball levers is thus transmittedto the governor 7 ter cnnbe lo mol the thrust-ro be. suv. 20D
